1 Overview
1.1 Introduction
The Park Air T6-AV100 VHF 100 W Power Amplifier enhances the capabilities of Park Air T6-TV VHF 50 W
Transmitters and Park Air T6-TRV VHF 50 W Transceivers1 for the most challenging of RF environments.
The T6 Amplifier is placed in series with a standard T6 Transmitter or Transceiver and provides amplification of
the R F output up to 100 W. The amplifier provides class-leading RF performance whilst integrated into a
small light package.
The T6 VHF 100 W Power Amplifier features:
Class-leading RF co-location performance
Intelligent built-in-test to monitor its own performance and allow RF pass through to safeguard
communications
Extended service interval and service lifetime
Tool-free installation into the Park Air C4 Cabinet
No materials specified in the Restriction of Hazardous Substances Directive
The T6 VHF 100 W Power Amplifier accessories:
Mounting adaptor for 19” cabinets.
Associated accessories are shown in 8.1 Table of associated equipment
1.1.1 Standalone operation
The T6 VHF Amplifier can compliment standalone T6 Transmitters or Transceivers with the addition of a suitable
AC and/or DC supply, an antenna and a Park Air S2 Hand Microphone or Park Air S2 Headset.
Installation details are shown in 3.1 Standalone installation.
1. The T6 50 W Transmitters/Transceivers must be operating a firmware version of 65-00000841/10.8.0
or later.

1.1.2 Park Air C4 Cabinet installation
The T6 Radios, T6 Amplifiers and Park Air Z4 Filters are specifically designed to fit the C4 Cabinet. The T6 Amplifier
requires a 2U 19” partition. The C4 Cabinet can accommodate various combinations of T6 Radios, T6 Amplifiers
and Z4 Filters.
The C4 family of cabinets has the following capacity options:
22U, 32U or 42U capacity.
Typical T6 Radio and T6 Amplifier installation (rear):
Installation details are shown in 3.2 Park Air C4 Cabinet installation.

1.2.3 T6 VHF Amplifier documentation
1.2.4 T6 VHF Amplifier spares
1.3 Features
1.3.1 Built-in-test
The T6 Amplifier continually monitors its own environment and performance. Fault detection alerts the radio to
enter a ‘Reduced Service’ state, decreasing the power output and alerting the operator with diagnostic
information before loss of service occurs. See 7.2 Park Air T6 VHF 100 W Power Amplifier features and benefits.
1.3.2 Internal RF bypass
On failure the T6 Amplifier automatically switches into bypass mode. This allows transmission to continue at a
reduced power, see 7.2 Park Air T6 VHF 100 W Power Amplifier features and benefits.
